Horseshoe crabs have persisted for more than 200 million years, and fossil forms date to 450 years ago. The American horseshoe crab (Limulus polyphemus), one of four extant species, is found along the Atlantic coastline North America ranging from Alabama Maine, USA with another distinct population on coasts Campeche, Yucatán Quintana Roo in Peninsula, México. Although tolerates broad environmental conditions, exploitation habitat loss threaten species. We assessed conservation status by...
Mass extinctions have disrupted the evolutionary history of several species, and with it discovery novel proteins biomedical biotechnological value. However, Limulus polyphemus, a xiphosuran marine arthropod, is "living fossil" 480-million-year-old lineage. To explore this legacy, rMe'exLec1, 13.15 kDa tandem-repeat lectin from L. was studied. Named after ancient Maya term "Me'ex" ("spider fish"), Identified in genome, recombinantly expressed Escherichia coli, purified via nickel affinity...
Abstract According to an International Union for Conservation of Nature (IUCN) Red List assessment (RLA), the American horseshoe crab ( Limulus polyphemus ), iconic coastal species, is at risk extirpation in some regions within its range where small and vulnerable populations occur. However, RLA does not consider future status beyond viability attempt identify conservation necessary effectively mitigate threats recover species full ecological functionality. To aid planning IUCN developed...
Abstract Post-copulatory female accompaniment by males is often interpreted as mate guarding. However, several alternative hypotheses for the function of have received little attention. We analysed potential functions post-copulatory in whiptail lizards, Aspidoscelis costata, comparing 23 accompanied females and 54 unaccompanied field. Male companions closely followed 1 to 2 days around ovulation, after which became unreceptive. Unaccompanied were all stages reproductive cycle, including 12...
Abstract In this paper, horseshoe crab exoskeleton and exuviae were collected on the coasts of Yucatan physicochemical studies carried out. Samples from different sections taken to evaluate chitin content properties in order be compared with exuviae. The isolation was realized by chemical processes involving deproteinization, demineralization discoloration. Physicochemical extracted both sources terms characterization analysis particular achieved under EDX, FTIR calorimetric techniques (DSC...
Timing of sexual activity by males and females is a critical aspect mating systems. We analyzed whether reproduction in western Mexican whiptail lizards, Aspidoscelis costata, on tropical Pacific island Mexico seasonal or continuous, it linked to certain meteorological factors. Macroscopic microscopic analyses monthly samples gonads showed that reproductive cycles were (February–September) significantly associated with day length. Necropsies did not evidence an overlap between successive...
We describe polymerase chain reaction primers and amplification conditions for 13 microsatellite DNA loci isolated from two bisexual species of whiptail lizards Aspidoscelis costata huico inornata. Primers were tested on either 16 or 48 individuals A. c. and/or 26 Ten the also against a panel 31 additional taxa. detected three to nine alleles per locus in four 19 inornata, with observed heterozygosity ranging 0.60 0.87 0.15 1.00, respectively. These will be an important resource surveys...
Among the main issues in pharmacological treatment of depression are wide variation response to antidepressants among individual patients and lack indexes that allow prediction which drug will be effective a particular case. We evaluated whether differential sensitivity amitriptyline is related dichotomous categorization individuals on basis their behavioral responses two common paradigms used evaluate potential tricyclic drugs as antidepressants. Hence, we categorized cohort 38 female rats...
